In this work, were investigated about the investigation of the frequency-dependent change in the character of the dielectric permeability and the tangent of dielectric loss angles of the biocomposites type LDPE + x vol.% FB obtained by fish bone fillers adding to the matrix of low density polyethylene and the bionanocomposites type LDPE + x vol.% FB + 1 vol.% Al with adding to this mixture 1 vol.% aluminum nanoparticles size 50 nm, calculation the actual and imaginary parts of the dielectric permeability of these materials, and the investigation of frequency change of electrical conductivity of both bio and bionanocomposites. It has been established that the dielectric permeability of biocomposites practically does not change in the frequency range 0–103 kHz.
